DSP (digital signal processor)-controlled, line-output converter

Harley Davidson 23.5-24 EQ Curve Correction Tool

The plug-and-play option now has a PAC TR7 Trigger module for installation for pops and time delays (suggest programming for 15 seconds delay). How to program one here

This revolutionary DSP (digital signal processor)-controlled line-output converter automatically detects your factory stereo system's frequency response and phase. It allows you to integrate it into a more fun, modern entertainment setup!

SIGNAL RESTORATION

In the pursuit to get the best sound possible from your stereo system that features both factory and aftermarket gear, KEYLOC’s patent-pending KEY™ algorithm automatically detects and analyzes crossovers, EQ, time delay, and all-pass filters present, and then it will level-match the left and right audio channels. Once analyzed, it corrects these various filters to give you the smoothest frequency response possible, giving you a clean, uncolored audio signal for your aftermarket gear.

HEAR IT YOURSELF

To hear what you’ve done, cycle the EQ correction on and off with a single push of the KEYLOC’s “KEY” button – hear the before and after! Additionally, if KEYLOC detects any all-pass filters or factory time delay, you can defeat the correction (from the menu) and keep the imaging of the factory source unit. By keeping the correction filter active, KEYLOC will counteract either of these factory effects, so you can use an external audio processor to dial in a one-seat tune for the ultimate sound experience.

FIND THE FREQUENCY

News flash! Factory audio systems don’t always deliver a full-range signal on every speaker wire. This makes it tough to hook up an aftermarket amp and get the sound you want—until now.

Attach the factory speaker wire to the KEYLOC input and play the FREE recommended test tones (below). Then read the KEYLOC’s LEDs – you’ll instantly know what frequencies are available from any particular pair of speaker wires (Low 20-200Hz / Mid 200-2kHz / High 2k-20kHz). Get Test Tones Here!

You will have to program this once it is installed.  Watch the video!
